1. Pest Control

Looking for a solution to aphids, caterpillars and beetles? Try sprinkling a bit of diatomaceous earth on the soil around your plants. The diatomaceous earth dehydrates insects by sucking up the lipids from their exoskeletons - kind of gross - and kills them.

You can also use it for dealing with insects inside the home, like cockroaches, silverfish and fleas by placing powder near doorways and under furniture. Be sure to add another coat after mopping, or after a rain if you put any outside.

The most effective diatomaceaous earth for pest control is uncalcinated earth, which means it wasn't heated before packaging.
